So I thought I was hearing valvetrain noise coming from my car AGAIN as it was a "tick tick tick tick", but low and behold the noise has been narrowed down to my Purge Valve Solenoid. This solenoid is brand new, I mean like hardly even driven the car with it. I guess I know the solenoid is working, but I didn't remember it being that noisy. I can hear it over my HPFP and have hovered over the head multiple times to hear nothing but a "shhhhhhhhh" sound of the cams rolling across the rockers, can't even hear the valves really working/ticking at all which is what I like to hear.

Please excuse the dirty engine bay. Shes still a little greasy from recent maintenance and it never stops raining for one week here...
You can hear the distinct tick when I put the mic right next to it. Otherwise, what the camera picks up is just a mix of everything. In person I hear the solenoid over the HPFP.

 

Can you make a video?? an is it constant or intermittent? My car was makin some crazy tickin noises while I was on the highway one day, pulled over an could still hear it extremely loud.. took it to the dealership a few days later, they didnt hear it, an I didn't hear it again after that... but I was pretty freaked for those couple of days

 

Yea, sure. Give me a few, gotta grab the phone. And it is a constant repetitive tick.

 

Is the video at cold startup still?

 

My car sounds like that

 

Sounds like normal cold startup to me, but it's hard to tell from the video. Plus I watched it on my phone

 

sounds like my car too on cold startup. It goes back to the normal slow click once it warms up.

 

Eh, car was warm when It was doing it before. I had just got done logging it not too long ago. Then I started working on my jeep and jumpstarted it from the cobalt.
